Pentax intros K-50 and K-500 DSLRs, Q7 mirrorless camera

When it rains, it pours -- we knew Pentax was due for new interchangeable lens cameras, but it just surprised us by unveiling three of them at once. The mid-range K-50 and entry K-500 DSLRs at the front of the pack represent slight upgrades to the 16-megapixel K-30 on the inside, with both gaining a higher ISO 51,200 sensitivity and Eye-Fi card support. They mostly differ on the outside. The K-50 keeps the K-30's weather sealing, lithium batteries and extreme color customization; the K-500 caters to the budget crowd by going without weatherproofing, running on AA batteries and shipping only in black. Both bodies are available in stores this July, starting at $600 for a K-500 with an 18-55m kit lens and $780 for a similarly equipped K-50.

The smallest camera of the bunch, the Q7, may be the most intriguing. While the mirrorless body still shoots at the 12.4 megapixels of the Q10, it upgrades to a larger 1/1.7-inch sensor that delivers a big performance boost -- sensitivity has jumped to ISO 12,800, and there's faster autofocusing to boot. Pentax also touts a faster shot-to-shot time, better image stabilization and Eye-Fi support. The Q7 will cost the same $500 in kit form as its ancestor does today, although photographers will have to be patient when the tiny camera doesn't hit retail until August.
